Draw Back type
  • DRAW BACK type collet chuck used mainly on CNC turning machines, special purpose machines, etc.
  • Suitable for machining bar material and mandrel.
  • High clamping accuracy, high speed and high rigidity.
  • The installation is the same as “Thru-hole power chuck” and they are replaceable with each other.
  • This is a completely sealed design, which prevents coolant and chips from entering the spindle.
  • J is the hole diameter of blank draw nut, K is the maximum thread specification, and it could be customized.
